TRANSMISSION ADJUSTMENT
Planting population rate changes are made
at the end mounted transmission. The
planter is designed to allow simple, rapid
changes in sprockets to obtain the desired
planting population. By removing the lynch
pins on the hexagon shafts, sprockets can
be interchanged with those from the sprocket
storage rod bolted to the transmission.
Chain tension is controlled by a spring-
loaded dual sprocket idler. The idler
assembly is adjusted with a ratchet arm. This
arm has a release position to remove spring
tension for replacing sprockets. The amount
of spring tension on the chain can be
controlled by the ratchet arm.
The planting rate chart on the following
pages of this section will aid you in selecting
the correct sprocket combinations.
OPTIONAL EQUIPMENT
An optional hydraulic drive for the turbofan is
available. You must then double check that
there is adequate oil flow for the turbofan to
run at 500 rpm. Use an rpm gauge to check,
placing it at the center of the lower pulley.
A vacuum gauge may also be mounted to
the turbofan. (The vacuum gauge is standard
equipment when ordering the hydraulic
drive).
